6.4 twentytwentyfour How can I create sub-sub-menu dropdowns?

I recommend asking at https://www.ads-software.com/support/theme/twentytwentyfour/#new-post so its developers and support community can help you with this.

Thanks for the prompt reply t-p! I’ll do that but do you know if the 6.4 software allows sub-sub-menus?

There is no limit to how deep sub-menus go in WordPress, from sub-sub-menus to sub-sub-sub-sub-menus and beyond.

The limitation is in deep your theme was designed to display those sub-menus.

Many thanks James! Do you know if theme twenty twenty-four can display sub-sub-menus and, if so, how?
